What scientists found beneath the Labrador seafloor could change permafrost mapping May 21, 2026 at 12:10AM

Scientists have uncovered frozen soil layers on the seafloor along Canada's Labrador coast, a discovery challenging previous assumptions about subsea permafrost. Direct evidence, including ice-rich sediment cores and unique seabed formations, confirms its presence. This finding suggests permafrost may exist in unexpected southern marine environments, prompting a wider re-evaluation of Arctic coastlines.
